The workflow checks a stored SendPulse Access Token. If expired it requests a new token and saves it.\n3. It checks for or creates SendPulse mailing lists for emails and phones, then adds the contact to the appropriate lists.\n4. An AI model generates a personalized, professional welcome email and the workflow sends it via SendPulse SMTP.\n5. The AI also generates a short, friendly SMS which is sent through SendPulse SMS.\n\n## Setup steps\n- [ ] Add your SendPulse **Client ID** and **Client Secret** to the **Workflow Configuration**.\n- [ ] Configure **mailingListWithEmails**, **mailingListWithPhones**, **senderName**, **senderEmail**, **smsSender**, **routeCountryCode** and **routeType**.\n- [ ] Create a **tokens** data table with columns: **hash** (string), **accessToken** (string), **tokenExpiry** (stirng).\n- [ ] Add your **OpenAI API Key** to the **OpenAI Chat Model** node.\n- [ ] Point your website form to the workflow webhook (customer-registration) to POST name, email or phone number.\n- [ ] Test with a sample submission and confirm the contact is added and both email or SMS are delivered."
